Intermittent one way audio - CME -SIP Trunk

[shiblyibrahim]

Hey Guys,

We are experiencing intermittent one way audios. So to verifiy for evey cal show voip rtp connection was used.

By this we found all the one way audio was caused by only one IP address and the good calls have a different IP.

Has anyone experienced this, if so what was the solution.

This is the output

oIP RTP active connections OK CALL

No. CallId     dstCallId  LocalRTP RmtRTP LocalIP           RemoteIP

The call in red gives issues.

One way audio is almost always a network routing issue. The one ip involved has a routing issue with the other ip phone sub nets

Thanks Jeremia, do you know how I could resolve this. I have contact my SP to see if we can get that particular IP address banned or so.
